The present invention relates to usovershenstvovannogo Ripper tip and in particular to the Ripper tip for loosening or splitting of solid ground. In accordance with a preferred embodiment of the present invention is applied in the extraction of opal, if you want to go through the hard ground in the attempt to discover the opal.

BACKGROUND of INVENTION

Loosening the lugs are typically used where comes across very monolithic rock or solid ground to pass and to loosen the purpose of discovery and extraction of precious stones such as opal. Loosening the lug includes a protective cover, which is usually attached to the front of nakonechnyi bulldozer, while in the bow of the protective pads attached plot Ripper tooth, obespeennymi opening of the ground usually at a depth of approximately 300 mm at a time. In the case of opal mining loosened rock is popped, while prospectors check it for signs of opal. In addition, the Ripper tooth can be removable. The author drew attention to some problems associated with such conventional Ripper tips.

First, in some cases, the removable sections of the Ripper teeth are attached to the Ripper tip can be rotated. PR the problem with having a rotary Ripper tooth is during operation, the top soil can get into the area between the stem loosening of the tooth and the casing Ripper tip. It is in the case of the rotary shaft leads to considerable wear, which may eventually cause metal fatigue and breakage under high nagruzke. Another problem is that the Ripper tooth has a tendency to move and knock during operation, which is also undesirable. Another problem is that in those cases when in the area surrounding the stem loosening of the tooth, accumulate fine clay and other similar material, and Ripper tooth is almost impossible to remove. In addition, the currently used Ripper tips with rotary Ripper tooth of the road in the manufacture, and their use is limited to only a small area.

The author of the present invention also found that Podravka extremely important "angle", i.e. the angle at which the Ripper tip performs a bomb it. Usually when you bomb it the angle defined by the angle at which departs the end of a pole tip of the bulldozer, because this rack is installed Ripper tip. Position rack bulldozer is regulated, however, its movement is limited, and often the desired angle of inclination is not reachable.

If the angle of inclination of which is sustained fashion tooth is too large, that is, at a very large angle between the longitudinal axis of the Ripper tooth and the surface of the ground, ripping the tip starts to knock, which can cause increased wear of the Ripper tooth, metal fatigue and possible damage to loosening of the tooth. Under such conditions, the load on the bulldozer increases, which leads to increased fuel consumption. Moreover, if the angle is too large, the fore part of the top of the Ripper tooth may get stuck, and Ripper tooth can be extracted. In General, when an improper angle, the efficiency of splitting rock Ripper tip falls. In fact, it was found that even very small changes of the angle of the Ripper tooth can significantly affect the efficiency of Podravka.

The purpose of the present invention is to solve at least some of the above problems, or to offer appropriate alternative.

DESCRIPTION of the PREFERRED N IS KEROV IMPLEMENTATION of the PRESENT INVENTION

Listed below are the drawings detailed description of the invention. Although in the description are typical examples of the implementation of the present invention, other embodiments of the present invention, and modifications in the embodiments of the present invention, without departing however from the scope and essence of the invention. In the description and drawings are used sequentially numbered.

According to three different embodiments of the present invention 10A, 10b and 10C, the invention relates to usovershenstvovannogo Ripper tip. Figure 1-7 shows the Ripper tip 10A, Fig-10 shows the Ripper tip 10b, and 11-12 shows a Ripper tip 10C. On Fig shows the bulldozer 12, to which can be attached to any of the Ripper tips. For krasoti first loosening the lug 10A will be described in detail, but will not be given the description of the similar elements of the other Ripper tips, but the numbering of similar items will be stored.

Figure 1-5 shows the Ripper tip according to the present invention 10A, which includes a protective cover 14 and a removable ripping tooth 16. During operation, the protective cover 14 is attached to the front tip of the bulldozer 18 bulldozer 12 or other earth-moving mechanism as shown is as Fig. Bulldozers of this type are well known and therefore the description is not all elements of the bulldozer 12, as with the exception of the front tip of the bulldozer 18 other elements do not perform any functions relating to the present invention.

The protective cover 14 is held in place by means of a pair is made opposite to each other, the locking holes 20 located in the rear of the hollow part 22 of the protective pads 14, which together with the locking pin 24 is fixed protective cover 14 Ripper tip 10A to free the front tip of the bulldozer 18. It should be understood that the protective cover 14 can be interfaced with any existing stem loosening of the tip, and that in addition to the locking pin 24, and made opposite to each other, the locking holes 20 may be used by any other fixture.

Front protective pads Ripper tip 14 is a monolithic piece 26. This monolithic part 26 creates mass and to some extent helps in loosening. First of all, in a monolithic part 26 made nest or boring a hole 28, in which is tightly inserted removable ripping tooth 16. Boring the hole 28 has a square cross-section and along the axis of the walls that taper inward so that the size of the cross section of boring holes 28 near the hollow part 22 is less than the size of the RA adjacent end of the Ripper tooth. All four sides of the slot 28 is rounded to provide strength.

Removable ripping tooth 16 consists of the head section 30 and rod 32. The shape of the rod 32 removable Ripper tooth 14 conforms to the shape of the slot 28 of the protective pads 12, i.e. the walls of the shaft are also narrowing and its cross-section has a square shape with rounded corners. This allows the rod 32 is firmly seated in the socket 28 with a fixed connection. Professionals it is clear that a fixed connection is extremely durable and will prevent twisting of the rod removable ripping tooth 16 and to ensure that no particles will not fall between the wall of the stem 32 and the adjacent wall of the slot 28. In accordance with a preferred embodiment of the present invention, the socket 28 is molded, which ensures the compliance of its dimensions to the dimensions of the rod 32.

After fixation loosening of the tooth in the socket 28 of the head portion 30 moves along the centerline from monolithic part 26 of the Ripper tip and therefore narrows under the same angle as a monolithic part 26. Head portion 30 and Ripper tooth did not come out too far beyond the protective lining 14, which prevents it from damage or breakage during loosening. At the end of the removable ripping tooth 16 has a pointed tip 34, which can be manufactured by the linen of high-strength material, for example, tungsten. Pointed tip 34 may simply be welded to the removable ripping tooth 16. High strength tapered tip 34 provides the passage even through the solid rock and minimization problems currently used sharpened tips Ripper tip, which wear out quickly.

When attaching removable ripping tooth 16 to the protective plate 14, as described above, achieves many advantages.

First, it reduces knocking during operation because the ripping tooth 16 is fixed, and the wear of the ripping tooth 16 is also reduced, so the dirt is no longer enters the gap between the rod and Ripper tooth 32 and the socket 28. This is the main problem turning loosening of teeth, in which the particles to RUB against the corresponding surfaces during operation, which leads to metal fatigue and possible failure ripping tooth 16.

Secondly, the fixed connection provides an easier dismantling of the ripping tooth 16, so fine clay no longer accumulate around the stem loosening of the tooth 32. As mentioned in the preamble of the present invention, it often prevents the removal of the Ripper tooth. In this case, when the gap area having a constriction, a Ripper tooth just fall out, and it will short the TKO described below.

Thirdly, the use of Ripper tip is not limited by the present invention and it can be used in conjunction with other mechanisms, including both small and large bulldozer rippers, end cutters on the dumps the bucket of a dragline, excavator buckets, excavator, and loosening of the teeth of the bucket loader. In addition, the manufacture of such tips are not expensive.

To ensure fixation of removable ripping tooth 16 in the protective plate 14 during operation can also be used a secondary means of fixation, which in accordance with the preferred embodiment of the present invention is the locking pin 36. Figure 6-7 shows the Ripper tip 10 including such a fixing pin 36. In the ripping tooth 16 is made groove 38, running across its bottom side so that when it is fully inserted into the slot 28, the axis of the groove 38 coincides with the axis of the hole 40, which passes across a monolithic part 26 of the protective pads 12. After alignment of the locking pin 36 may simply be inserted through the aligned holes to lock the Ripper tooth.

It is believed that fixation loosening of the tooth in the socket sufficiently fixed connection, but if necessary, you can use a secondary locking means. Prior to insertion into the bore of a pin which may be shrinking in the transverse direction, and after inserting it expands, which provides a more tight fit. All other aspects of the Ripper tip depicted in Fig.6-7, is identical to the aspects of the Ripper tip depicted in the previous figures.

Remove ripping tooth 16 of the protective pads 12 can be performed in a variety of ways. The ripping tooth 16 has a ledge or shoulder 42, coming out from the head section 30 of the ripping tooth 16, and this ledge serves to facilitate the removal of ripping tooth 16. The shoulder 42 is in order for it to take any instrument and to pull a tooth in case of wear Ripper tooth after prolonged use.

In another case, a ripping tooth 16 can be removed by inserting a pusher (not shown) or other similar object through the hole to eject 44 leading from the hollow part 22 of the protective pads 14 to the socket 28. Experts clear that when ripping tooth 16 is clamped in the slot 28, such action will cause the ripping tooth 16 to exit from the slot 28.

It should be understood that the configuration of the ripping tooth 16 can vary. In this case, the pointed tip 34 includes a dual inner cone before you go to the point. This feature, together with the high strength properties of the tip 34 ensures that even through the most solid scalin the Yu breed can pass with minimal slippage and problems related wear currently used sharpened tips Ripper tip, simplified. Can also be used with other types of nozzles, for example, one-cone tip, or curved tip. In addition, the cross section of stem loosening of the tooth 32 and openings in the protective lining 28 should not be square, but may be any other shape, for example, triangular or round, providing a fixed connection.

You should also understand that the possible configuration variants of the slot 28 in the end of the stem loosening of the tooth 32. For example, in the drawings shows the gap 46 between the end of the rod 32 and the end of the boring of the hole 28, and holes for the push-44. Another option concerns the tapering of the walls of the boring holes 28, providing just increase the distance to the hollow part 22, as is the case in the second and third embodiments of the present invention. Another option involves no gap at all between the hollow part 22 of the Ripper tip 12 and boring a hole 28.

When using removable Ripper tooth, which, as described in the present invention, during operation, is in a fixed state, it was found that the above problems relating to knock Ripper tip,wear, loosening of teeth, the destruction of the Ripper tooth, and other related problems were significantly reduced. In particular, the use of such loosening lugs gives you the advantage of saving up to 10% due to the reduction of the load on the bulldozer, save up to 50% of the time because of its ability to loosen the rocky ground accurately, and total ecomony, including production costs, up to 10-20%.

On Fig-9 shows the Ripper tip 10b in accordance with a second embodiment of the present invention, which, as described above, has the same fixed connection ripping tooth 16, but which also provides a tilt angle.

This angle can be seen on figure 10, which shows Ripper tip 10b of the present invention, and a dotted line for comparison illustrates the usual loosening the lug 48. Specialists understand that a monolithic part of a normal Ripper tip 48 is located along the same axial line, and a protective cover 14, and the solid portion 26 of the Ripper tip 10b Assembly moves upward from the protective lining 14. Specialists understand that, if monolithic piece 26 moves up, then inserted it ripping tooth 16 will be rotated relative to the protective lining 14.

In the drawings shows the angle of the monolithic part 26, the cat who, which was determined experimentally, and the optimal value of which is equal to approximately 6 from the longitudinal centerline of the casing of the protective lining. From this angle the external surface of the Ripper tooth becomes almost parallel to the layers of rock pound. Usually, but not always, these layers parallel to the surface of the soil.

The existing loosening the lugs can be modified to look like a Ripper tip depicted in fig.10b. For example, in accordance with the first embodiment of the present invention at the point of transition between the protective plate 14 and monolithic part 26 of the Ripper tip 10A can be made the cut. The cut is performed at a selected angle relative to the longitudinal centerline of the protective lining. Specialists understand that after welding monolithic part to the unbent end of the protective pads 14 it will go at an angle corresponding to the angle of cut.

It was found that, when the Ripper tooth departs from this angle, the tip loosens the soil more effectively than it has done hitherto known Ripper tips that gives such preimuschetva as reducing knock, wear, loosening of teeth, and the load on the bulldozer. It should be understood that the angle at which the monolithic piece 26 moves away from the protective lining 14 may vary depending on the operations performed.

Figure 11-2 shows the Ripper tip 10C, the appropriate third aspect of the present invention. Loosening the lug 10C differs from the Ripper tip 10b is a little fact that besides the fact that monolithic piece 26 moves at an angle from the Ripper tip, it extends along the longitudinal centerline relative to the protective pads 12, as is the case in loosening the lug 10A according to the first embodiment of the present invention. In this case, the angle of inclination is achieved through the slot 28, is molded at a selected angle relative to the solid portion 26 of the Ripper tip so that the ripping tooth 16 may extend beyond this angle. The figure uses the same item numbers.

The angle is designed so that the ripping tooth 16 is tilted slightly upwards, to go parallel to the ground. The advantages of this angle in accordance with a third embodiment of the present invention have been described above.

Although not shown, it should be understood that this Ripper tip 10C may also include a locking pin for additional fixing, as described above.

According to a third embodiment of the present invention Ripper tip 10A may also include a set angle of the Ripper tooth, which is achieved by performing a direct cut is the transition point between the protective plate 12 and monolithic part 26 and just by replacing a monolithic part of the plot with through boring a hole.

In addition to the mentioned in the present invention may provide other advantages and improvements, which, however, do not go beyond its scope. Although the invention is shown and described as the most practical and preferred embodiment, it is understood that there may be deviations which, however, are within the scope and essence of the present invention, which should not be limited to the details disclosed here, but should correspond to the total volume formula isbreene to encompass all equivalent devices and apparatus.
